12 years agoadd uatomic_generic.h, use it for common definitions
Paolo Bonzini [Mon, 1 Mar 2010 18:57:00 +0000 (13:57 -0500)] 
add uatomic_generic.h, use it for common definitions

uatomic_generic.h can be included by uatomic_arch_*.h to provide useful
default definitions.  uatomic_arch_*.h can define whatever builtins
it wants to override, then uatomic_generic.h will provide what is not
already defined, as follows:

- uatomic_cmpxchg will use __sync_val_compare_and_swap builtins;

- uatomic_add_return will use __sync_fetch_and_add if uatomic_arch_*.h
did not provide a definition of uatomic_cmpxchg.  If it did, we assume
__sync builtins are buggy or otherwise undesirable on this platform,
so uatomic_generic.h will implement uatomic_add_return in terms of
uatomic_cmpxchg too.

- uatomic_xchg is like uatomic_add_return.  However, since GCC does
not provide an adequate builtin, it needs to use a compare-and-swap
loop using __sync_bool_compare_and_swap if uatomic_cmpxchg is not
provided.

- uatomic_sub_return/uatomic_add/uatomic_sub will be implemented
in terms of uatomic_add_return;

- uatomic_inc/uatomic_dec will be implemented in terms of uatomic_add.

After this patch, uatomic_generic.h is already used for the latter two
categories.  The next patch will use uatomic_generic.h whenever there is
no assembly code involved, or otherwise it makes no difference to use
uatomic_generic.h.  We keep custom per-arch macros to provide support for
compilers back to early GCC 3.x versions; however future ports may
not have this limitation.

The hunk in tests/test_uatomic.c is only needed for bisectability
and will be removed later.

Support sparcv9 32-bit build

From: David Miller <davem@davemloft.net>
Subject: Re: [ltt-dev] Sparc64 support added to Userspace RCU

From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>
Date: Thu, 22 Oct 2009 15:57:53 -0400

> Feedback is welcome,

__sparc_v8__ does not mean 64-bit longs or pointers as implied here:

"v8" was the last 32-bit standard of the cpu architecture.

Otherwise looks fine.

Although this port won't be very useful until it can be built in
32-bit mode.  As most applications on sparc64 systems are still
32-bit.  Like on powerpc, people only rarely build things 64-bit on
sparc64.

You need to build with "-Wa,-Av9a" on the GCC command line for that
case so that the assembler allows the v9 instructions emitted by your
macros, even when building for 32-bit.

Hope this helps.

12 years agocross-compilation: use $host instead of $target
Pierre-Marc Fournier [Wed, 11 Nov 2009 22:48:40 +0000 (17:48 -0500)] 
cross-compilation: use $host instead of $target

$target should be used only when building a compiler. It indicates
the target system for which the compiler will build executables.

$host is the variable that should be used to indicate the type of
system the package we are compiling now will run on.

Also, update the README to say to use --host instead of --target.
